Key result
HEART, GRACE, or TIMI scores identify low-risk ED patients with <1% MACE, minimizing emergent imaging.
Why the study?
Does risk stratification using HEART, GRACE, and TIMI scores reduce the need for emergent cardiac imaging tests in EDOU chest pain patients?
Observational (n=986)
No

p-value: p=>0.05
Chest pain risk stratification using clinical decision tools, especially the HEART score, can safely minimize the need for emergent cardiac imaging tests in the ED observation unit.

Supports risk stratification in ED chest pain; hypothesis-generating and requires RCTs before changing imaging practice.
Wang et al. (2016) conducted an observational in Chest pain (n=986). Clinical decision tool scores (HEART, GRACE, TIMI) vs. Emergent cardiac imaging tests vs no emergent tests was evaluated on Major adverse cardiac event (MACE) rates (p=>0.05). Risk stratification of ED observation unit chest pain patients using HEART, GRACE, or TIMI scores identified low-risk patients with <1% MACE occurrence, minimizing the need for emergent imaging.
